To aZZ whom it may concern.-

Be it known that we, STEPHEN H. FRENCH and WILLIAM J. lVIALTBY, citizensof the United States, residing at Baird, in the county of Callahan andState of Texas, have invented anew and useful Improvementin \Vheel-Hubs,of which the following is a description.

This invention relates to that class of wheelhubs which are made up ofseveral parts in order that they may be cast in metal; and the object ofthe invention is to adapt the mortise-piece of the hub to be castindependently of the flanges, to form a positive clamp for theshoulders, and to protect the bearing from sand.

To this end our invention consists in the construction and combinationof parts forming a wheel-hub, hereinafter described and claimed,reference being bad to the accompanying drawings, in which Figure 1 is asideelevation of a portion of an axle and our hub mounted thereon. Fig.2 is a longitudinal vertical section of the same, and Fig. 3 is a detailface view of the mortisepiece.

A represents the axle, having the usual arm, B, screw-threaded at itsouter end to receive the nut O, which retains the wheel-hub on the arm.

D is the body of the hub, grooved around its inner end, to form theflange E, which, passing under the sand-guard F, forms the sand-shield.The guard F is a common hood secured to the axle to extend over theinner end of the hub around the upper half thereof. This prevents sandfrom falling at the end of the hub, and whatever sand works off at theend of the band falls into the groove in the hub behind the flange E,and is likely to be dropped to the ground before it can work over theflange. To aid in effecting this result, the body of the hub at thebottom of the groove is conical, tapering away from the flange, thusforming the widest space be tween the guard F and the said body at theend of the guard farthest from the end of the hub.

The outer end of the body is provided with a flange, G, serving as ashoulder, against which a collar, H, may abut.

This collar may be held from turning on the body by any usual means-suchas a feather or spline, Jpro 'ecting from the body into a slot in thecollar.

K is a ring niortised radially in at one face, smaller than the collarH, and placed with its whole side against the same, the open side of itsmortises being toward the inner end of the hub, thus forming a shoulder,L, for a shoulder of the spoke M to rest on.

N is a washer fitted to rest against the tenons and a portion of thebodies of the spokes. Ois the inner'end collar, of the same size as theouter end collar, H, and internally screw-threaded, forming a nut toengage a screw on the body D. This nut is notched at its edges toreceive a spanner-wrench or the end of a set-tool, to be turned onto oroff from the body. By this means any amount of force may be applied topress the spokes into the mortises and to hold them between the collar Hand washer N.

The spokes are supported where they should be on the outer or dishingside of the wheel on the shoulder L, and their inner faces are smooth,whereby common punched washers, N, will fit them, and cause the nut tobear without grinding on the wood of the spokes. If a great and suddenstrain were suddenly brought to bear circumferentially on this wheel,themortised collar and spokes therein would yield and turn a little on thebody between the collars before the spokes would break, thus removingone source of danger which has been common to wheels.

What we claim as our invention, and desire to secure by Letters Patent,is

1. The combination, with an axle and a hood or guard fixed thereon, of ahub reduced at one .end and provided with a flange at the outer end ofsaid reduction, and a collar or nut having a flange projecting over thefree end of said hood or guard, said hood or guard fitting over saidreduction of hub, substantially as and for the purpose set forth.

2. The combination of the hub -body D, provided with the shoulder G nearits outer end and a screw-thread along the inner portion, the spline Jnear said shoulder, the

slotted collar H, fitted to said shoulder and threaded body D,substantially as and for the spline, the removable ring K, smaller thanpurpose set forth.

the collar and having radial niortises in one r T side, and shoulders Lin alignment with said 5 mortises, upon which shoulders rest shout iders of the spokes, the washer N, fitted lVitnesses: against the ring K,and the internally-serew- A.
